As the head of the executive branch, the president has broad discretion in the enforcement of immigration laws. He can place a moratorium on the deportation of DREAM Act students, he can end SCOMM, and he can drastically reduce the thousands of family separations that are the inevitable result of his current approach. His unwillingness to do these things, which have been repeatedly called for by Presente.org and numerous other groups, has nothing to do with Congress and everything to do with burnishing his enforcement credentials for the 2012 election.
